I.—Note on some Vertebrate Remains collected in the Fayûm Egypt, in 1906

Extract

The collecting expedition to the Fayüm in the Spring of 1906 did not result in the discovery of any striking new forms, but nevertheless a large number of specimens was obtained, some of which add considerably to our knowledge of species already imperfectly described. Of these specimens the most important are: (1) An associated skull and mandible of Palœomastodon wintoni with the upper and lower dentition, including the tusks, in perfect preservation; an atlas, humerus, radius, part of an ulna, and some vertebræ of the same individual were also found, and confirm the determinations that had previously been made from isolated examples. (2) A beautifully preserved mandible of a very young Palœomastodon, probably the same species. In this specimen the two posterior milk-teeth are in position, while the anterior one is represented by its empty alveolus. Beneath the two milk molars are the germs of pm. 3 and pm. 4, almost ready to replace them vertically in the ordinary way.
